Yes totally right, I can see how a bow might aid pick up but not to clear the infield, that’s just an odd thing to say. It’s come full circle on bat faces that’s all, back in the 80’s they were flat, then a period of big bows, now a lot of manufacturers sell flat blades and a lot of the pros use them-GM for example are most if not all flat.
As for low or high middles rather than the wickets we play on maybe your stance and if you have low or high hands would be just as important.
